To nl! whom. it 'may concern:

Vie it known th'at l, linen hnnnrron, a citizen of the United States, residing at lellevue, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Im rovenients in liegenerator Systems for y-Product Coke- Ovens, and do declare that the following is a lull,:clear, and exact description of the invention, which will enablel others skilled in the art to which it appertains to make and use the same.A

lily invention relates to an improved regenerator systemfor luy-product coke ovens, and the object of the invention is to provide an oven which, among other things, contains a means for supplying a continuous quantity of heated air to the fuel burners therein, and obviating the necessity of reversing the het gases in the combustionchamhers of such ovens, as is now commonlydone, thus making a continuous heating oven and considerably increasing the elliciency and capacity of the oven, all as hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional elevation longitudinally of one end orhall oi a coke oven and iny improved regenerator. therefor, being broken away at the left and which omitted part is an exact duplicate of that shown erl cepting that it is reversed and arranged back to .bach thereto. This view is taken on line l-l, Figs. 2 ande and shows a con'rhnstion chamber and a regenerator chamber in open conniunication therewith and with its valve-x arranged to permit the escape of waste gases to the oil'heat flue leading to the stack. Fig. 2 is a crossl section corresponding to line 2&2, Fig. 1 ol one complete oven. or colic-chamber with a pair of regenerator chambers below, said view representing only. what may be considered one unit in a serie..v ol similar units which are combined in any desired number. Fig.. 3 is a vertical seeL tional elevation centrally ol the coke chaniber and through a regenerator chamber which is taking in air to supply the eoinhustion; hainbers and heing on line SYM-3, lfigs. 2 and 4 ol' the regenerator next adjacent. to ihe one shown in Fig. l.

improved system as applied to a horizontal type of oven and whic is the preferred construction, but it is likewise ap ilicable to the vertical flue type of oven by s ight modificatidn of the air tlues to the burners. ln Fig. 1, the sectional view shown discloses the regenerator discharging the hot Waste gases from the combustion chambers, and Fig. .3 shows the regenerate-r next adjacent to that of Fig. 1, taking in air to vsupply the con1bustion chambers'. j

The broad idea herein is to maintain conetant combustion in the combustion chamhers of the oven and at the same time utilize the hot wiste gases from the combustion chambers to continuously heat the air supply passing to said combustion chambers, and all without reversing the hot gases in the combustion chambers as now practiced, but by a reversal of the waste gases in the regenerators alone, tlius saving inthe quan-A tity of gas required in coking of coal as well as making a continuous heating oven.

In my system as thus shown l' employ a series of regenerator chambers or regenerators indicated by C and C respectively, arranged in airs at each end or half of each coke chamlier or oven A', so that when air is passing through one in one direction, hot waste products are passing out through thL` other in the opposite direction, the same being` adapted to alternate in this respect, lirst, to store up the heat of the waste gases, and second, to heat the air for conihustion purposes when reversal is eliected. To this end, an' enters regenerator C from the out side in Fig. 3, sage a wherein valve l'l'is closed as to the olli heat llue S leading to a stack (not shown), while in Fig. l the the regenerator C next adjoiningr hy valve ll and the exit to the stack is. open for the products of combustion coming Ahach through regenerator C', and. heatingthe cheek-work huilt-in open'worli and walls ol said passages as said waste products pass to the stack. Thus l store the said regenerator chambers C and C alternately with heat and then ahstored heat in the air that flous reversely tl'n'ough the. saine `llues onward to combustion `chambers D of the oven to snply combustion. ln reality, each oven A has fou'r regenerator chambers arranged with i ino chambers underneath each end of the oven, the drawings only shovnng one half, or in other words, one snifI of a system.

as indicated hy open air pas-v Valves H and IH eachv control both the air inlet a, and the exit 4 for-their respective regenerators and valve G and G likewise "control both the hot inlet E from their which opens into a horizontal passage A3 running transversely of the oven and common to all in the series, land exit of these gases is throu h openings B tto each regenervator7 sa C w en'the valve therefor isopen.

From t ence, the gasesrun hack and forth to the exit 4 at the bottom. During this time, thc4 air is pass' U, in opposite direction through. regenerator and out. at opening E to horizontal air flue F across thefront of the oven from. Which-it is sup lied to the com-l bustion chambesl'D and t e burners D by :vertical fines F and 'ports K at the side thereof?A By movin the slide dempers G K and G and. H and 'l the air' and o'ases are of a setan`d by Ineaniof horizontal reversed from one rcgenerator to the other or waste gas cross ihre A and the 1ct air cross flue F, a ilexible arrangement is ob` tained, whereby. two or more ovens can work on one set of regenerators, if desired.

Suitable doors are provided for each end ofthe o ven as usual 'although not shown, and it will be understood that the construction of ,the oven is otherwise as ordinary. and is sup lied with all the ,other necessary. details an arts to make it complete and practical. "Vvnat I claim isz- Y. 1. In by-product coke ovens, a series of ovens having a double regenerator beneath each half thereof and provided Withcom ssage' generators arrangedl in Ainto both said cross discharge flue an inlet)l v bustion chambers having both waste product and air vintake passages connecting all said t combustion chambers and said regenerators,I

and 'means to control the direction of flow to said regenerators 'to and from said passages, and whereby continuous heating of the said ovehs is obtained with a reversal of How' in the rfgeneators only.

2. n a regeneratorsystem for cokeovens,

a bank ofbvens, each having combustion chambers provided withk discharge: assages for the products of combustion an n airA intake passages for the burners, and a plurality of regenerator chambers 'for each oven havlng separate .v'alved` intakes and. outlets adapted .to reverse the flow of waste'products and air alternately from one regenerator chamber to another without reversing the'ilow of waste products or air 'within the combustion chambers.

3. ln a regenerator system for by-product i coke ovens, the ovensand -burners therefor having the return flue regeneratorchambers for heating the air supply by the waste prod uct-s comprising a series .of such chambers to each ovennrranged in pairs, and provid ed with meansto-reverse the ow of said waste products and -air alternately through pairs of said chambers and-thereby maintain a oontinuous flow of heated air to saidburners'f- A 4. A. series of coke ovens arranged' side by side. and, 'having combustion chambers between `them and a cross discharge flue con- .nested wltll said co-mbristion chambers and. separate air lues to said combustion ,cham-f bers having an' inlet lgross passage connected with said lair lues, in co'nbination Withxre p irs and lo ening cross passa e and having valved meansA to open and c ose the same separately.
